Switch imports back to case sensitive sorting

[jakebailey]

Fixes #51617

As of the latest nightly VS Code TypeScript extension, we seem to handle things correctly.

If we also want Organize Imports to work, I can add in the necessary newlines or changes + eslint rule to enforce that, I was just trying to do more of a revert. But, I think people just want their editors to work better, so I can just add that change in here.

Ugh, can't even enable declaration sorting in ESLint because it requires you to also be picky about the kinds of imports themselves:

Which, organize imports has no idea about. Would really just like to be using dprint to do this and leave eslint out of the picture.

[jakebailey]

eslint-plugin-import can do this, but, it also doesn't match organize imports.

[rbuckton]

Maybe we need an eslint-plugin-organize-imports that uses our logic.

At this point I am strongly preferring #52090.
